Price receipt
We read xAI's own pricing page on Aug 12, 2026 and found grok-4.6 Grok 4.6 New grok-4.6 Our flagship model for code a listed with a price on the same row — that read is where the number above comes from, recorded as a new model. We keep the page text we read; its content hash is 9f17ff66dc.
Overview
xAI's smartest model — builds on Grok 4.5 with a focus on long-running agents and more ambitious interactive and visual work, and matches GPT-5.6 Sol on the Artificial Analysis Intelligence Index. 500K context, configurable reasoning effort. $2/$6 per 1M tokens; prompts above 200K tokens bill at the long-context tier of $4/$12.
Capabilities
struck through = not supportedBenchmark performance
accuracy % · higher is betterWe hold no per-benchmark accuracy scores for this model yet, so it has no accuracy average. That is a gap in our coverage, not a sign the model is untested — independent evaluators often publish a composite index for a new model long before releasing its per-benchmark numbers. The percentile above is its standing across the independent composites below.
- AA Intelligence Index: 60.9 (Artificial Analysis composite across reasoning, knowledge and coding evals)
- AA Agentic Index: 58.7 (Tool use, planning, autonomy)
- AA-Omniscience Index: 30.5 (−100–100)
- GDPval-AA v2: 1749.2 ELO (Real-world work tasks, human baseline = 1000)
- LMSYS Chatbot Arena: 1463.6 ELO (Human preference)
- Ranks #4 of 154 comparably-measured models by percentile score, across 5 independent measurements
- Ranks #85 of 154 comparably-tested models by normalized performance per dollar
